Yarn, yarn forming process, protective textile, knitting method and equipment

ABSTRACT

The present invention relates to a yarn and a yarn forming process, further relates to a protective textile produced by using the yarn and a knitting method therefor, and additionally relates to textile equipment for knitting the protective textile. The present invention discloses a yarn, wherein a core filament of the yarn uses a tungsten wire, which is covered at the center of an outer-layer yarn. A protective textile knitted by using the foregoing tungsten-wire yarn may be obtained by using single-yarn knitting, or by using double-yarn knitting by mixing another yarn. A single shuttle or two-shuttle knitting of the textile equipment may be used in the knitting method. Technical effects of the protective textile are that the protective textile knitted by using the tungsten wire as a core filament has a higher protection level, is lighter and thinner, better fit hand skin, and is operated more flexibly.

TECHNICAL FIELD

The present invention relates to a yarn and a yarn forming process thereof, further relates to a protective textile produced by using the yarn and a knitting method thereof, and additionally relates to textile equipment for knitting the protective textile.

BACKGROUND OF THE INVENTION

In recent years, there are a greater variety of protective textiles, and the development of protective textiles trends toward high and new technology industries and has become an important sign for advancements in textile technology at present. As safety awareness of people keeps increasing, demands for protective textiles keep growing on a daily basis, making it unavoidable to develop and research protective textiles. In view of the fact that people are highly susceptible to hand injuries, scholars at home and abroad are paying more attention to the research on performance of protective textiles for hands.

Currently, the American Society for Testing and Materials has updated the standard for cut resistant gloves, and has proposed the standard ANSI/ISEA 105-2016 (with cut resistant levels from A1 to A9), making the concept of cut resistant gloves more thorough and precise.

For the standard ANSI/ISEA 105-2016, a series of cut resistant yarns such as a polyethylene (PE) fiber, a steel wire, a basalt fiber, a glass fiber, a Kevlar fireproof fiber, and a Dyneema fiber are contained in cut resistant gloves in the prior art. However, practice has proved that after the foregoing fibers are manufactured into gloves, a series of negative effects, such as unstable cut resistant levels, allergy that occurs on hand skin because of fibers breaking easily, poor washability, and a poor feel of thick cut resistant gloves, may occur.

Existing yarn forming processes mainly involve three types of yarns: a core-spun yarn, a twisted yarn, and a covered yarn. The specific yarn forming processes may be shown in FIG. 1, FIG. 2, and FIG. 3. The main original material of existing cut resistant knitted gloves is a single complex yarn formed by combining yarns such as a steel wire, a basalt fiber, a glass fiber, a long PE fiber, a short PE fiber, a long Kevlar fireproof fiber, a short Kevlar fireproof fiber, a long Dyneema fiber, a short Dyneema fiber, a long aramid fiber, a short aramid fiber, a polyester fiber, a polyamide fiber, a spandex fiber, a carbon fiber, a copper fiber, and a silver fiber. By using one or more complex yarns, to achieve that the gloves can be used for operations in special environments, yarns such as an acrylic fiber, a chenille yarn, a carbon fiber, a copper fiber, a silver fiber, and a bamboo fiber may further be added for knitting in a glove knitting process. After yarn formation, the gloves are knitted with a single layer or double layers by using an automatic seamless knitting machine. This knitting method is applicable to machines with various gauges such as 7 G, 10 G, 13 G, 15 G, 18 G, and 24 G.

However, a cut resistant level is low in the foregoing methods. The seamless knitted gloves manufactured by adding yarns such as a polyamide fiber, a polyester fiber, and a spandex fiber to a long PE fiber can generally reach a cut resistant level only between A1 to A3 in ANSI cut testing, and the gloves are thick and heavy with a higher cut resistant level. As known from feedback information of markets, all gloves that can reach the ANSI cut resistant level A4 and above, are mainly made of a PE fiber, a Kevlar fireproof fiber, or an aramid fiber added with materials such as a glass fiber, a basalt fiber and a steel wire. However, after multiple yarns are combined, knitted gloves tend to have a stiff feel, and cannot ensure a desirable feel during operations.

In addition, skin allergy may further be caused. To increase the cut resistance of gloves, many commercially available gloves contain a glass fiber. However, after being knitted into gloves, glass fibers may break after a series of bending of a palm and fingers. The broken glass fibers can prick hand skin, and easily cause inflammation and an itch in hand skin, and may cause allergy to some extent. Cut resistant gloves are a high-value-added product, and are hardly disposed immediately after being worn only once, and may be worn again after appropriate washing. Experiments show that the breaking degree of glass fibers in gloves containing a glass fiber material reaches 83.7% after washing. Consequently, more serious allergy of hand skin may occur when the gloves are worn again.

Advantages of the present invention are as follows:

Under same conditions, by comparing yarns manufactured by using a tungsten wire and one of a glass fiber, a steel wire, a Dyneema fiber, or a basalt fiber as a cut resistant material, cut resistant levels of knitted gloves are obviously different. Cut resistance data obtained by the laboratory of our company is as follows:

By testing cut resistance according to the standard ANSI/ISEA 105-2016, gloves knitted by using a yarn combining a tungsten wire as a cut resistant yarn and materials such as a PE fiber, an aramid fiber, a Kevlar fireproof fiber, a polyester fiber, a polyamide fiber, a cotton yarn, an acrylic fiber, a chenille yarn, a carbon fiber, a copper fiber, a silver fiber or/and a bamboo fiber can generally reach a cut resistant level from A3 to A5 with a weight of 1000 g to 2200 g.

By comparison, by testing cut resistance according to the standard ANSI/ISEA 105-2016, gloves knitted by using a yarn combining a glass fiber, a steel wire, a Dyneema fiber, or a basalt fiber of a same specification as a cut resistant yarn with materials such as a PE fiber, an aramid fiber, a Kevlar fireproof fiber, a polyester fiber, a polyamide fiber, a cotton yarn, an acrylic fiber, a chenille yarn, a carbon fiber, a copper fiber, a silver fiber or/and a bamboo fiber can generally reach a cut resistant level from A2 to A4 with a weight of 500 g to 1500 g.

The cross-sectional diameter of the tungsten wire is only 18 microns to 40 microns. The cross-sectional diameters of a steel wire and a basalt fiber are 30 microns to 60 microns. The cross-sectional diameters of a glass fiber and a Dyneema fiber are even greater than those of a steel wire and a basalt fiber. Therefore, for a same cut resistant level, gloves knitted by using a tungsten wire are lighter and thinner than gloves knitted by using a glass fiber, a steel wire or a basalt fiber, and can better fit hand skin, and can be operated more flexibly. For a same cut resistant level, the gloves knitted by using the tungsten wire as a cut resistant material are thinner than the gloves knitted by using a conventional cut resistant material, and the gloves knitted by using a tungsten wire that have an ANSI cut resistant level A5 are thinner than the gloves knitted by using a conventional cut resistant material that have an ANSI cut resistant level A4, and can better fit hand skin.

Kevlar is a brand name of an aramid fiber material product developed by the American company DuPont. The original name of the material is “poly-paraphenylene terephthalamide”, and the repetitive unit of the chemical formula of Kevlar is -[—CO—C6H4-CONH—C6H4-NH—]-, where amide groups connected to a benzene ring have a para-position structure (a meta-position structure is another product with a brand name Nomex, commonly known as a fireproof fiber).

Dyneema is a well-known brand among ultra-high-molecular-weight polyethylene (UHMwPE) fiber products, and is a registered trademark of the company DSM. Dyneema can be used for commodities such as accident prevention gloves, textile fibers, semi-processed plastic fibers, and ropes.

In the following embodiments, the diameter of a tungsten wire in a yarn that contains a tungsten wire and is used in a protective textile is 18 microns to 40 microns, corresponding to levels A3 to A5 in the standard ANSI/ISEA 105-2016. That is, when the diameter of the used tungsten wire is 18 microns, the cut resistant level of the protective textile is A3. When the diameter of the used tungsten wire is 30 microns, the cut resistant level of the protective textile is A4. When the diameter of the used tungsten wire is 40 microns, the cut resistant level of the protective textile is A5.
